I'm 39 and as much as I like my 4-string EB, a DB seems very cool for certain situations (e.g., playing in church). I feel that I'm a motivated self-learner who is resourceful. I believe that I have developed an efficient physical approach to playing the EB - without the benefit of an instructor. With hard work and study, could I learn solid DB technique through books, videos, online forums and perhaps the bit of EB technique that carries over to DB? Or is this nearly impossible without an instructor? I live a little over an hour from the nearest music store that even sells DB's, so finding a good instructor probably wouldn't be easy. Also, I play EB with a light touch - have worked hard to learn to play relaxed and remain tension free (still working on relaxation actually). So will I have to pluck considerably harder to generate an audible tone from a DB - it seems like some DB'ers are plucking hard. In terms of actually buying a DB, I'm only a window shopper at this point, but I often see DB's and wish to have one.
